A barely used pair of DT770 80 ohm circumaurals, they've been burned in. They are the 80ohm version, which doesn't require an amp as much as the 250 ohm version. I have since sold the lambskin earpads, so it comes with stock cloth earpads instead. The box, headphones and 1/4 plug adapter are included.

The unit runs from a single 9V battery and internally the supply voltage is used to create a pair of +4.5 and -4.5V power lines.

Alternatively external power supplies can be connected with supply voltages between 6V and 12V DC. The external supply voltage is internally splitted to create a pair of +3..+6V and -3..-6V power lines.

The total buffer capacity is 4000 uF to lower the effective battery impedance.

For amplification two single AD8610 opamps are used for maximal sonic performance.(No dual or quad-opamps!)

The 3.5 mm sockets are silver-plated.

Inside the signal path only metal-resistors and high-quality film-capacitors are used (polypropylene).

The enclosure is made entirely of aluminium.

The Amp does not come with anything but the Amp itself, but I can toss in the 9V battery it was using anyways.

Looking for $160.

Shipping/Handling

With all the headphones, will clean and disinfect them before shipping/selling it.

I'm located in Toronto and Markham, can deliver it within the GTA(reasonably within) for free, or pickup downtown on certain days or in Markham for certain days. Basic untracked Shipping will be free, adding tracking/expedited/ExpressPost will cost whatever Canada Post charges, willing to pay half.

I am in Toronto and looking to buy these headphones (you haven't sold them yet have you?) date for pickup can be discussed but I am willing to pay $180 cash if you are willing to meet me at a subway station close to me for the transaction. Email me at aarcv2@gmail.com if this works for you.
